For reliable fieldbus function, line termination must be arranged in both ends of the
transmission line. For a G5 instrument, at the end of the cable, a connector with line
termination should be used. For all other G5 Instruments, connection without line
termination should be used.
For configuration of the adaptor, a GSD file (VISH0F83.GSD) is available and should
be installed in the master.
Select the 8 words output module + 2 x 16 words input modules + one 8 words input
module. This will give 16 bytes of output data and 80 bytes of input data. The PLC set-
up should match this exactly including the order of the input modules.
